IMPROVED MACHINE FOR BENDING- FIFTH-WHEELS.

lThe Schedule referred to in these Letters Patent 4and making part ofthe same.

-To all whom 'it ma/y concern:

N ew'Lisbon, in the county of Columbiana, and Stateof Ohio, have inventecertain vnew and useful Improveinents in Machines for BendingFifth-Wheels; and I do hereby declare that the following is a full,clear, and-exact description thereof, reference being had to theaccompanying drawings, and tothe letters of reference marked thereon,which form a part of this specification.

The nature of my invention consists in the construction and generalarrangement of a machine for bending platform wagon-circles andfifth-wheels.

l In order to enable others skilled in the art to which my inventionappertains, to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawings, in whichlFigure l is a longitudinal vertical section, and

Figure 2 is a plan View of my machine.

Figure 3 is a bottom view of the same.

A represents the circular bed of the machine, on each side ofwhich'extends a bar, B, of any suitable dimensions.

Around the upper portion of the circular bed A, and resting on the barslB, is a circular disk, O, or base, 4the upper side of which is level,toHatten the surface of the iron to be bent.

The under side ofthe base Gis provided with cogs, placed incircular-form, and ,in one of the bars B, which is hollow, is placed ashaft, D, provided with-a pinion or nutre-wheel, E, that gears in saidcogs.

'The shaft D is, atjrits outer end, provided with a crank, F, to beturned by hand, and also with a wheel, G, that is to be connected, by abelt, to an engine.

Bynow turning =the shaft D, by any means desired, it will be seen thatthe base C is made to revolve around its axis, the bed A.

On top of the base C, and around the upper edge of the circular bed A,isplaced the dial H, around the circumference of which the'ironis tb bebent. This dial may be exchanged for another of larger or smallerdiameter, whereby the diameter of the wagon-circle can readily bechanged, and thus any desired circle be bent on the same machine.

On top of the bed A is placed a cap or plate, I, the

outer edges of which lap over the inner edgesA of the dial vH, and ascrew, J', being passed through the centre. into the bed A, the base Gand dial Hare held down.

A pin in the-upper side of the base U, which enters a hole in the dialH, causes said dial to be revolved with the base, while a similar pin inthe bed A, that enters a hole in the cap I, prevents v the cap fromrevolving.

Around the screw J, above the ca'p I, is placed a collar or sleeve, K,having a projection on one side, in whichthe inner end of atumbling-shaft, L, has its bearing, the other or outer end of said shafthaving its bearing in a' stud or standard, M, near the louter edge ofthe base O.

0n the shaft L` is placed a lever, N, to hold the iron down on the base.

The other one of the bars B has a projection on its outer end, whichextends beyond and above theouter edge of the base C, and through theAsaid projection is passed a rod or bar, O, which runs above and parallelwith the base C.

This rod, at its inner end, on'the under side,h s provided with a pinand roller, P, and can be set at any desired point in the bar B, bymeans of the setiV screw a, so as to roll any desired size of circle. f

Through the projecting part of the bar B above mentioned, is an uprightpost, R," through the upper lend of which runs a rod, S, parallel withthe rod or bar O, said rod S being set at any point desired, by means ofthe set-'screw,b.

The inner end of the rod S is provided with a head or enlargemennthronghwhich a vertical rod, d, passesv downward, said rod being alsoadjustable by means of the set-screw e. Y

Through the lower end ofthe rod al,` at right angles,

runs another rod, f, which is adjusted by means or' the set-screw t',through the lower end ofthe todd.-

On the rod f, on the inner side of "tl1e.post d, re-

volves the split wheel h.

By these devices, I am enabled to set the split wheel hso" as to rollany desired angle on the iron, and the split wheel lcan be adjusted toany size, by

spreading the wheel iu lengthening the rod j`,.on which it revolves. lThe post R passes entirely through 'the bar B, and

is held up by'a spring, g, whereby the wheel is enalbled to readily passany clip or obstruction on th'e iron, and is brought down again by atreadleattach'ed to the lower end of the' post It.

Having thus fully described my invention,

What I claim as new, and desire t0 secure by LettersIatent, is p 1. Thecombination and arrangement of the circular bed A, bars-B B, base C,dial H, cap I, and screw J, all constructed and connected as described,and for y vthe purposes set forth.

2. 4The.arrangement ofthe collar K, shaft L, stand ard M, and lever N,with the screw J and base C, substantially as'and for the purpose setforth.

3. The arrangement vof the splitwheel' h, revolving on the pin j, andinadeadjustable by means of said pin, and the posts d S R, and spring y,with-the'bar B, substantially in the manner and for thejpurposxe hereindescribed.

In testimony that'I claim the foregoing as my own, I aix my signature,in presence of two witnesses.
